Ultra-Low Power Wake-Up Radios

  • Chapter

Part of the Integrated Circuits and Systems book series (ICIR)


There is a growing class of event-driven devices that require instant-on wireless connectivity, but only use the radio to communicate intermittently throughout their lifetime. Home automation devices and most wellness monitors fall into this class, only using or needing their radios when prompted by an event. In these applications, the radios dominate the amount of energy consumed from the batteries. More specifically, the energy spent synchronizing the radios, or maintaining a connected state, dominates, as opposed to the energy spent communicating data.


  • Ultra-low power
  • Wake-up radio
